AudioJungle gives some requirements for the music audio files. These are: 16 bit, 44.1 kHz for WAV and MP3 audios plus 320 kbps for MP3. Also demands the audio not to be clipped, that is maximum peak 0 dBTP.
But there are and other parameters which has to be considered during the Mastering (or even during Mixing). The most important is the loudness, measured in LUFS.
I can say that according to some standards or practices the loudness of the audios can be grouped to four groups.
a. Program Loudness around -23/-24 LUFS Int, for films, broadcasting, TV.
b. Program Loudness arround -16/-15/-14 LUFS Int, for Mobile, iTunes (radio), CD and general streaming.
c. Program Loudness around -11 LUFS Int, for iTunes (Store), SoundCloud? Etc.
d. Program Loudness around -9 LUFS Int. I have seen such suggestions in this forum as appropriate loudness for AJ.
Except of the Program Loudness there are and other parameters like loudness range (LRA), dynamic range (DR), Short Term Loudness, Max Momentary Loudness, Stereo Balance etc.
For the genre of the music that I compose (classical string quartets and small ensembles) and I want to upload to AJ, it is impossible to go beyond -12 LUFS Int, as the high compression destroys the dynamic range of the music.
Now my questions are:
- Is it a good idea to master the audio to -16/-15 LUFS Int, keeping the peak <-1dBTP and LRA around 9 LU?
- Is allowed to write in the description of the item the technical characteristics of the audio?
- Do the reviewers pay attention to the technical characteristics of the audios?
Thanks for reading
